.e `Be it`knowngthatfl,.NELs e e a ycitiz'enofV the UnitedStates, residing at Braddock, `-in lthe county-of Emmons and State of-North Dakota, have inventedcertainnew anduseliul Improvements in Draft- Equalizers; and I do hereby declare thefolflowing to be a full, clear, and exact description of the invention, suchv as will enable others skilled in the n' art` to which `it appertains tomake and use the same.

My invention has lfor its object to provide an `improved draft equalizer and, ,tof this end,` it consistsof the novel? devices andcornbinations vof devices hereinafterfdescribed and defined in theclaims. l i

v In the d`rawingsthe` device is shownas a four-horse equalizer` arrangedv to permitthe horses ato be `driven abreast, but ther principles of construction 'involved therein may be incorporated in draft equalizers' of4 fdillerent horse, capacity.`

This improved draft equalizer is adapted for use in connection with diierent kinds of 40 on the land ll."

" n j ofthe parts of the impved dma @quaianc izer, the numeral 1,` indicates a pair of parallel, vertically spaced metallic brackets having, at their rear ends, parallel,` vertically spaced anchor vflanges 2 and inwardly projecting spacing .'langes B; The spacing flanges 3 are engageableone with the other,

to roperly space the brackets'l, and the ior flanges 12" embrace the horizontal r. B; fermi, l 1

dicate klike .parts throughout the several views i M `framel 5 by.y angle brackets 6. The brackets 1 `are secured to the bar 4, for differentiaterall adgustments thereon, by .nut equipped H8 ,extend from endfto end ofthe bar 4 and v 'e permit various adjustments of the brackets liwith. respect to the bar-4, in Vorder to `secure the proper line. of draft.- `A spacing Ythimlo'le Slis inserted between the fouterend portions` of thebrackets l and issecured `theretoloy a nut equipped bolt 10fpassed .thro-ugh said thimble and brackets'.

A relatively long'main equaliziiig leverl 11 is' extended 4 transversely between i the brackets l and isintermediately pivotedthereto,

by a nut equippedbolt 1Q. The long endiof :thefmain equalizing lever-11 extends outward ;or away from the formed, furrow..

Substantially parallel with the m'ainfequalizing` lever l11 isa relatively shortsupplemental equalizi'ng lever 13,.one end of which u' projects between the viorward -ends of ,the .brackets 1- and is secured thereto,lfor longitudinal .adjustmentyby a nut `equipped Abolt 14 adapted to be passedthrough. anyone pair Vof-,fvertically alined-perforations 15 formed in thev brackets 1.o i i ,f i i Two horse eveners 16 and 17 are secured, respecti-velyato. `the `long' 1 end mf 'the i )main equalizing-lever 11 and to the inner end of the supplemental equalizing lever 13. The eveners 16 and 17 are provided, respectively, with rearwardly projecting, relatively long and short links 1S and 19. The links 18 and 19 are secured, respectively, to the main equalizing lever 11 and supplemental equalkizing lever 13, by nut equipped bolts 20 and Q1 passed through perforations in said links and through any one of a plurality of longitudinally spaced perforations 22 and 23 formed,` respectively, in the main and supplemental equalizing levers. By longitudinally adjusting the eveners 16 and 17 on the main and supplemental equalizing levers, the entire draft strain may be equalized between the four horses. U-shape wearing plates 24 and 25, respectively, embrace the main and supplemental equalizing levers 11 and 13, at points where they are attached to the brackets 1.

The supplemental equalizing lever 13 is l ratentec'iiyov.24, 1914, r ;:"Appiicati0nied angusti/anais'. serial im.r 784,734.

the brackets.V l by a clevis 27, the prongs of which embracesaid brackets and arepiyot all .secured thereto by short 'nut equippedy bo ts 28 having their heads countersunk in izing levers for. adjustment toward and fromv theinner faces of the brackets 1, as best shownin Fig. 2; IThe 'other end of the chain 26'is attached tothe intermediate portion of the supplemental equal-izing lever 13 bya clevis 29, the prongs of which embrace the v'ranged to run over a grooved roller 32jourvso `als

saidl lever.' and are pivotally secured thereto byga nut equipped bolt As shown, the wearingplat'e 25v is extended between the prongs of the clevis 29. To permit longitudinal adjustment of the cable 26, the same is' connected to the clevis 29 by an eye bolt l31 vhaving screw threaded engagement with the transverse portion ofsaid clevis. The ,intermediatevportion of the cable 26 isarnaled at 33 to the prongs of a U-shaped metal plate '34 which embrace the short end of the main equalizing lever 1l and are rig- I idly bolted thereto. p

"A flexible cable 35, inthe form of a chain, isprovided Vto limit the forward swinging movement of the long end of the lever l1 and thereby prevent one teamfr-.om pulling too far ahead of the other. The rear end ofthis'cable 35 is secured to the plow frame 5 'and the :forward end thereof is secured to a clevis 36, the prongs ofl which embrace the Vmainequalizingf lever ll'and are pivotally secured thereto by a bolt 37. A ground Yengaging, shoe 38, preferably constructed of spring metal, is attached to the long end of the equalizing lever 11, and supports the same'when the horses are at rest.
